Abstract

A plurality of vehicles with cameras and other sensors collect images and other data as a normal event, or upon demand, or when requested to do so by another vehicle, an occupant or a service center. Images may be permanently stored in the vehicles and indexed in a directory at a service center, so that the images may selectively sent to the service center or another vehicle without consuming storage space at the service center. When the service center is managing sufficient current data for an area, the service center generates a suspension signal to discard or instruct vehicles not to send further images from that area.

5. The method of claim 1, wherein:

said transmitting is to a central service center and identifies a destination for the image, which destination is other than the service center.

6. A method, performed by a computer system at a service center, for administering capturing of images by a plurality of cameras mounted on mobile units and for administering displaying of the images, comprising:

providing a database with identities of the mobile units;

receiving a request from a requestor for an image captured at a location; and

transmitting, by wireless communication, the request to one of the mobile units that is not the requestor.

7. The method of claim 6, further comprising:

generating the request of said transmitting step to include identification of the requester, to be used by the one of the mobile units as a destination address for direct wireless transmission of the image from the one of the mobile units to the requestor.

8. The method of claim 6, further comprising

providing a database correlation between identities of images, representations of the location where the images were captured and identities of the mobile units that captured and currently store the images;

extracting image availability from the database in response to the request;

when the image is available, said step of transmitting comprising a command to the one of the mobile units to remove the image from storage in the mobile unit and transmit the image to the service center; and

upon receipt of the image from the one of the mobile units, re-transmitting the image to the requester.

9. The method of claim 6, further comprising

providing a database correlation between identities of images, representations of the location where the images were captured and identities of the mobile units that captured and currently store the images;

extracting image availability from the database in response to the request;

when the image is not available, extracting the identity of a vehicle near the location and generating the request of said step of transmitting to include a command to the one of the mobile units to capture the image and transmit the image directly to the service center; and

upon receipt of the image from the one of the mobile units, retransmitting the image to the requestor.

10. The method of claim 6, further comprising

providing a database correlation between current locations of the mobile units, identities of images, representations of the location where the images were captured and identities of the mobile units that captured and currently store the images;

extracting image availability from the database in response to the request; and

when the image is not available, extracting the identity of a vehicle near the location and generating the request of said step of transmitting to include a command to the one of the mobile units to capture the image and transmit the image directly to the requester.

20. The method of claim 10, further comprising:

providing a directory of the identities of the images, the locations of different mobile units at the time that the different mobile units respectively captured the images, and the icons.

11. A method, performed by a computer system, for displaying images captured from a camera mounted on mobile units having a location sensor, comprising:

providing identities of the images;

displaying a map on a display;

displaying an icon on the map for each of at least some of the images;

correlating the icons to respective identities of the images; and

positioning each of the icons on the display screen at a location corresponding to the location of the mobile unit at the time that the corresponding mobile unit captured the image.

12. The method of claim 11, further comprising:

providing the icons as arrows; and

pointing each of the arrows in a direction related to a direction of image capture.

13. The method of claim 12, wherein

said pointing points the arrows in the moving direction of the mobile units that captured the image.

14. The method of claim 12, wherein

said pointing points the arrows in the direction of the camera that captured the image.

15. The method of claim 12, further comprising:

relating lengths of the arrows respectively to speeds of the mobile units that captured the corresponding images.

16. The method of claim 11, further comprising:

selecting an image for display on the display with a curser and one of the icons.

17. The method of claim 16, further comprising:

providing a directory of the identities of the images, the locations of respective capture of the images, and the icons; and

in response to said selecting, searching the directory and transmitting a request for the selected image according to results of said searching.

18. The method of claim 17, wherein:

said transmitting identifies a destination for the request as a central service center.

19. The method of claim 11, further comprising:

performing said method with a mobile unit;

receiving a request for an image by wireless transmission directly from a different mobile unit;

capturing and storing a plurality of video images;

providing a directory of the identities of the captured images, the locations of respective capture of the images; and

in response to said request, searching the directory and transmitting an image that corresponds to the request according to results of said searching.
